I'll be very interested in trying to stack mastery with a Destro PvP build. Stack mastery with gear, stack infernal embers with incinerate, and then hit for a bajillion with instant Soul Fire / Conflag. Spec into Grimoire of Sacrifice for fun. I'm guessing it would be the hard hitting ability in the game. I can almost hear the QQs now...

I dont like the wording on soul link, "All damage and healing the warlock takes is shared with her active demon" I hope that doesn't mean that we're mortal striking ourselves and instead of receiving 100% of all healing we'll now take 80% while our pet takes 20%

The level 75 tier actually raises some theorycrafting questions.
Lets just take Destruction as example:
Supremacy: More damage from pet, new possible beneficial abilities but otherwise just a flat damage increase
Service: A second demon, this will make your Soul Fire go down to 1 second cast time pretty often during theese 30 seconds
Sacrifice: Loss of "instant Soul Fire" but more burst which will be very good for a lot of fights, also scaling changes?

Another good question is if Soul Fire will even be usefull when its not instant and on the move, cause why would you want to waste infernal embers on Soul Fire instead of Conflagrate?

New - Curse of Enfeeblement - Level 17 Combines and replaces Curse of Weakness and Curse of Tongues to cause the target to deal 30% less physical damage and cast 30% slower for 30seconds. Less effective on dungeon and raid bosses. Instant. 4% of Base Mana.

Active: Splash affect is increased to 100% splash damage for 20 seconds, however the passive is dropped after this until the cooldown is reset. Instant. 2 Minute Cooldown.

Just a note, some of the Warlock abilities are names of old talents, for example the Destruction ability Fire and Brimstone, I put it as a new ability rather than a change since it's been completely revamped from a passive to an actual ability that's completely different to the current passive. The same can be said for pretty much anything else that is marked as ' New ' but has the same name as something already existing for Warlocks.

I dont like the wording on soul link, "All damage and healing the warlock takes is shared with her active demon" I hope that doesn't mean that we're mortal striking ourselves and instead of receiving 100% of all healing we'll now take 80% while our pet takes 20%

Pretty sure that's what it means. The Soul Link change and Demon Armor nerf (+10% healing in 5.0) is going to cut into our survivability pretty bad, but hopefully it's offset with all the self-healing we're getting. Frankly, I'd rather more active-defense like Spell Drain rather than a flat 20% damage reduction anyway.

Looks like everything will be GCD capped for Demonology rather quickly. Haste doesn't appear to be worth much for them.

Shadow Bolt was always a fast cast that got slower when you leveled up, and might be the same for Soul fire, which would make SF 4 sec at a higher level (if to match the 4 sec reduction from new emp imp)

I believe this is already the case at very low levels; SB's cast time actually increases steadily as you move up ranks. It might be that this tooltip is representative of the low rank version of the spell.

I recall someone from Blizzard saying that Demonology will use SB as filler, but that SB changes when entering Metamorphosis to something that sounds Demonic and melee'ish. Can't find the source yet. Think we, the Demonologists, will even have to be more melee than we already are, if they'll implement that. I'd like it, won't be bothered if they don't. Probably won't out-tank Bears anymore, but no reason not to try. (Muhaha)

EDIT: That topic seems to have disappeared >_>. Quite sure it was on the Blue Tracker and that I was awake at the moment I read it.

This, the mastery change (1% increased effect + 0.1% per point on Demonic Fury and Meta), and lack of damage buff on Meta makes me believe it will be "permanent".
Changes are probably going to happen, but if you're supposed to consume Demonic Fury for Meta, I don't see locks giving away +10% damage for 0 to 1% damage for the duration on Meta, except o AoE, perhaps.
Metamorphosis' tooltip could be wrong, and also it is too early to be able to tell anything so far anyways.

Lets leave Soul Fire and Shadow Bolt unchanged for now then.
However with a 4 second cast time on Soul Fire next expansion and possibility to get it down to global cooldown it better hit as a motherfucking truck compared to conflagrate or it will be completely useless
